Removing ntrboot

Once a flashcart has been flashed with ntrboot it is typically no longer usable as a DS flashcart (with the exception of certain flashcarts such as the Acekard 2i). It is possible to restore a flashrom file back to an ntrboot compatible flashcart to return it to it’s previous functionality. If you followed the ntrboot guide, you should have a copy of the flashrom backup.

Required hardware #

To remove ntrboot from your flashcart you will need:

  • A flashcard that has been flashed with ntrboot
  • A hacked DSi/3DS running ntrboot flasher in order to restore the flashrom backup to the flashcard
  • A flashrom backup of your flashcart. If you followed the ntrboot flashing guide, you should have this as a .bin file in the ntrboot folder from your flashcart MicroSD card or DSi/3DS SD card
  • If you do not have this backup, you may download the corresponding flashrom backup for your flashcart from the 3ds.hacks.guide ntrboot guide. These are available as magnet links and require torrent client like qBittorrent or Deluge to download them

Removing ntrboot #

You must have already followed dsi.cfw.guide and have a way of running homebrew.

  1. Place your flashcart’s flashrom backup in the ntrboot folder on your DSi SD card. Create this folder if it does not exist
  2. Download the ntrboot flasher to anywhere on your SD card
  3. Insert your SD card into a modded DSi, then run the ntrboot flasher
  4. Follow the instructions on screen. Select your cartridge from the list, then choose the Restore Flash option. After the restore has finished, your flashcart should now work as a DS flashcart again

You must have already followed 3ds.hacks.guide and have luma installed

  1. Place your flashcart’s flashrom backup in the ntrboot folder on your 3DS SD card. Create this folder if it does not exist.
  2. Download the ntrboot flasher to your SD card as sdmc:/luma/payloads/ntrboot_flasher.firm
  3. Insert your SD card into a modded 3DS. Power on your 3DS while holding START to open the luma chainloader, then select the ntrboot flasher
  4. Follow the instructions on screen. Select your cartridge from the list, then choose the Restore Flash option. After the restore has finished, your flashcart should now work as a DS flashcart again

Troubleshooting #

In some cases, the restore may fail. This may be due to either an incorrect flashrom backup file, or your flashcard may be incompatible with the restore. ntrboot uses a hardcoded name for restoring flashrom backups. If you renamed the .bin file and do not have the original name, you can create a flash dump which will create a .bin file of the correct name of which you can then use to rename your flashrom backup.

If you are unsure and require assistance you can ask in the DS(i) Mode Hacking Discord server.
